Title
(EN) STERILIZATION OF PLANT MATERIAL
(FR) STÉRILISATION DE MATÉRIEL VÉGÉTAL
Abstract
(EN)
Methods and apparatus for sterilizing plant material include disposing plant material in a sub-atmospheric pressure environment, dispersing a non-toxic, non-polymerizable gas into the sub-atmospheric pressure environment, applying an electric field to change the gas into cold plasma, and maintaining exposure of the plant material to the cold plasma until substantially sterilized plant material is obtained, wherein an amount of at least one active constituent in the plant material is substantially unchanged by the sterilizing. The plant material may be cannabis.
(FR)
La présente invention concerne des procédés et un appareil de stérilisation de matériel végétal comprenant le placement d'un matériel végétal dans un environnement à pression négative, la dispersion d'un gaz non toxique et non polymérisable dans l'environnement à pression négative, l'application d'un champ électrique pour changer le gaz en plasma froid, et le maintien de l'exposition du matériel végétal au plasma froid jusqu'à obtention d'un matériel végétal sensiblement stérilisé. Une quantité d'au moins un constituant actif dans le matériel végétal reste sensiblement inchangée par la stérilisation. Le matériel végétal peut être du cannabis.
